Systems and Methods for Using Tokenized and Dynamic Physical Checks

2. The method of claim 1, comprising activating the dynamic authentication code by activating circuitry of the physical check.

3. The method of claim 2, comprising deactivating the dynamic authentication code by deactivating the circuitry of the physical check after a period of time.

4. The method of claim 3, wherein deactivating the dynamic authentication code comprises causing the dynamic authentication code to become invisible.

5. The method of claim 3, wherein the period of time is determined by a life of a battery of the physical check that activates the circuitry of the physical check.

6. The method of claim 2, comprising activating the circuitry of the physical check based at least in part on moisture applied to a battery of the physical check.

7. The method of claim 2, wherein activating the dynamic authentication code comprises displaying the dynamic authentication code via a display device of the physical check.

8. The method of claim 2, comprising activating color coding of the dynamic authentication code using the circuitry of the physical check.

9. The method of claim 2, comprising activating the circuitry of the physical check based at least in part on a control signal received from a computing device.

10. The method of claim 9, wherein the dynamic authentication code is determined using an application executed by the computing device.

12. The method of claim 9, wherein activating the dynamic authentication code comprises sending a control signal from the computing device to the circuitry of the physical check to cause the dynamic authentication code to become visible.

13. The method of claim 9, comprising destroying a display device of the physical check in response to an invalid attempt to activate the dynamic authentication code using the computing device.

15. The physical check of claim 14, wherein the circuitry is configured to be deactivated after a period of time to deactivate the dynamic authentication code.

16. The physical check of claim 14, wherein the circuitry of the physical check is configured to be activated based at least in part on moisture applied to a battery of the physical check.

17. The physical check of claim 14, comprising a display device, wherein the circuitry of the physical check is configured to display the dynamic authentication code via the display device of the physical check.

18. The physical check of claim 14, wherein the circuitry of the physical check is configured to activate color coding of the dynamic authentication code.

20. The physical check authentication system of claim 19, wherein the dynamic authentication code comprises a single use tokenized version of an account number associated with the physical check.
